I was part of the first 10 to ship but haven't had a chance to post an update until now. Super fast shipping and ok packaging. Mine didn't have any damage, but I definitely agree with shipping them in a cardboard box/package to help protect them a little better. He also threw in some delrin rod already drilled for spacers, just cut to fit and it's all good. Got mine done fairly quickly, the worst part was finding screws long enough. If I had it to do again, I would get the kit, but it wasn't available when I ordered mine, so yeah.
I have mine mounted with the servo mounts/ears on top of the plate, with the horn side positioned closest to the gear case. Because of clearance issues, I had to go back to using a thinner aluminum hitec servo arm instead of my truty Robitronics, but it's not even an issue since the arm is so well protected now. It was a biotch to get everything mounted up correctly, but that's just the nature of the setup, not the fault of the part itself. With the plate firmly bolted into place, there is no movement or twist with a 333oz servo, and I doubt it would change much with an even higher torque servo. Other than protecting the servo horn, the clearance is the best feature it provides. It gives just as much as an ota or bta setup.
This weekend I ran my first comp with this setup and came in 1st, and many of my lines could not have been ran without the extra clearance this mount gave me. I also thrashed on the rig pretty hard in a few spots and the servo horn was unharmed! Great product Xirtic, I look forward to seeing what else you come up with in the future!
I'll post up some pics here sometime this week to show my setup.
